I thought y’all might be interested to see this. I’ve always heard that a dishwasher is rough on wood, so you would need to do things like wash wooden cutting boards by hand, etc. I was curious to see how a piece of jatoba (I think it’s also called Brazilian cherry) would fare in the dishwasher. I had a leftover piece from a project, so I applied a single coat of polyurethane to one half of it and left the other half unfinished. I threw it in the silverware basket of the dishwasher and forgot about it. Below is the result after 7 months and about 240 cycles through the dishwasher.

Here is the edge grain. Left side has the poly, right side is bare. The poly really made a difference in terms of retaining the color and such. It didn’t flake off at all.

Here is the face grain. Same orientation – poly on left, unfinished on right.

Here is the end grain at the unfinished side. I actually thought this is where the water would cause the most damage, but it’s pretty much in perfect shape.

Interesting, thanks for the info. My son washed his wooden purpleheart pencil, it did not make it. LOL.

I think having a couple pieces glued together would be another you should try because one piece doesn’t have anything restricting expansion on each side. Just a thought.

Great test, I’m impressed with the durability of the jatoba. Also impressed you forgot about the block of wood in your dishwasher for 7 months!

Do you the dry/heat cycle or air dry by just letting the dishes sit?

Yea, good question, conifur. We don’t use the electric (heated rod) drying. We just let them air dry.

Looks like the wood held up okay, but glue will fail quickly in the dishwasher. Even Titebond III “waterproof” glue will not hold up.

Yea, that’s a good point. I wasn’t thinking about the glue aspect.

I doubt that, according to Tight Bond site, Tite Bond II is water resistant/proof if not constantly emerged in water, Titebond III can withstand constant emergent in water. I use both for exterior projects, and never a problem with either, never used it for constant emergent in water.

Have you done conclusive testing to your above statement? I am sure Titebond has. If you have post it here.

First off, I am a retired chef, I would NEVER put one of my knifes in a dish washer to get banged around as much as you would a wood chisel or a hand plane.
2nd I dont use a cutting board much, but I have one, I use the plastic sheets, easier to fold and dump what is on it to the pan or kettle.
The cutting board is for heavy duty clever work.
I have 3, 1 pint spay bottles by my sink. #1 is a mix of H2O, ammonia and liquid dish soap, a degreaser, cost about 25 cents per pint. Nice for the grease splatter on the stove.
2nd one is H2O and dish soap, just to sprits something to wash it. Just doing 1 item like a fry pan or kettle.
3rd, bottle, dish soap, H2O and a touch of bleach for desanitising something.
If I use the wood cutting board, with meat or fowl on it, it gets sprayed with # 3, and washed off in hot water, if it is a really greasy piece of meat/fowl it gets # 1then rinsed off under hot H2O, and the hit with # 3 and washed off with hot water and left to air dry.
Never need to put it in a dish washer and wooden utensils get treated the same.

conifur:
Consider us educated, but when I sold my first cutting boards this year I wondered how many of them would eventually see a dishwasher. I suspect at least one or two. That is why I tried to use harder woods with more rot/weather resistance, and Titebond III.
It was nice to see that jatoba can be added to my list.

Not everyone has the background and knowledge in the kitchen as you.
Lots of people are one step above opening a chinese food container when it comes to the kitchen.
Eat, toss everything in that fancy machine over there for cleaning, press run and go do something else NOT in the kitchen…

More interesting to me was the fact that the varnish didn’t fail….I would have thought it would be toast after that punishment.

I have some beech and cherry spoons I have ran through the dishwasher w/ heat dry. Still together. Chalk up beech and cherry with the Brazilian Cherry.

Interesting find. I wonder if a piece of PINE would even still be in there after 7 months? :-)

When I first started woodworking for money I was pandering to all the coastal myrtlewood shops that sell to tourists. One big seller was wooden spoons which I made thousands of. I still have quite a few of them that I use on a regular basis and they go in the dishwasher with everything else and just require a bit of oil every few months. I will have to make some from jatoba as well and see how it goes. Thanks for the post.
